הַבֹּ֖קֶר א֑וֹר וְהָאֲנָשִׁ֣ים שֻׁלְּח֔וּ הֵ֖מָּה וַחֲמֹרֵיהֶֽם׃
With the first light of morning, the men were sent off with their pack animals.
Torah Temimah points to Yerushalmi Berachos 1:1.
Sefaria — Yerushalmi Berachos 1:1
הבקר אור. … הבקר אור כתיב – התורה קראה לאור בקר.
English: “As soon as the morning was light…” The Torah itself called the light “morning,” supporting the calculation of day from the appearance of light even before the sun is fully visible to observers.
On the daf / in context: The discussion reconciles the language of sunrise with the practical definition of the beginning of day.
Type of Learning: Derash on the verse (Yerushalmi) — not a formal named middah of the 13.
What Is Learned: The Torah’s language “the morning was light” legitimates treating the appearance of light as the start of day.
